TECHNICAL FIELD

The present invention relates to a pharmaceutical agent, particularly an agent of reducing amyloid beta (hereinafter referred to as Aβ) production, which is effective in the treatment of neurodegenerative diseases caused by Aβ, such as Alzheimer's disease and Down syndrome.

BACKGROUND ART

Alzheimer's disease is a disease characterized by degeneration and loss of neurons and also by the formation of senile plaques and neurofibrillary change. Presently, treatment of Alzheimer's disease is limited to symptomatic therapies with a symptom-improving agent represented by an acetylcholinesterase inhibitor, and the basic remedy which prevents progress of the disease has not been developed. A method of controlling the cause of onset of pathologic conditions needs to be developed for creation of the basic remedy of Alzheimer's disease.

Aβ protein, which is a metabolite of amyloid precursor protein (hereinafter referred to as APP), is considered to be greatly involved in degeneration and loss of neurons as well as onset of demential conditions (for example, see Non-Patent Document 1 and Non-Patent Document 2). The main components of Aβ protein are Aβ40 consisting of 40 amino acids and Aβ42 having two additional amino acids at the C-terminal. The Aβ40 and Aβ42 tend to aggregate (for example, see Non-Patent Document 3) and constitute main components of senile plaques (for example, Non-Patent Document 3, Non-Patent Document 4 and Non-Patent Document 5), and furthermore, it is known that mutations of APP and presenelin genes, which is observed in familial Alzheimer's disease, increase production of Aβ40 and Aβ42 (for example, see Non-Patent Document 6, Non-Patent Document 7 and Non-Patent Document 8). Therefore, compounds which reduce production of Aβ40 and Aβ42 are expected as an agent for controlling progress of Alzheimer's disease or for preventing the disease.

These Aβs are produced when APP is cleaved by beta secretase and subsequently clipped by gamma secretase. In consideration of this, creation of inhibitors of γ secretase and β secretase has been attempted for the purpose of reducing production of Aβs. Many of these secretase inhibitors already known are peptides or peptidomimetics such as L-685,458 (for example, see Non-Patent Document 9) and LY-411575 (for example, see Non-Patent Document 10, Non-Patent Document 11 and Non-Patent Document 12).

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention

As mentioned above, compounds which prevent production of Aβ40 and Aβ42 from APP are expected as an preventive or therapeutic agent for diseases caused by Aβ represented by Alzheimer's disease. However, non-peptide compounds which prevent production of Aβ40 and Aβ42 and have an excellent medicinal effect have not been known. Therefore, a novel low molecular compound that inhibits production of Aβ40 and Aβ42 is demanded.

That is, although the dehydration reaction of “Step 4-1” may vary depending on the starting material, and is not particularly limited as long as it can be effected under similar conditions as in this process and processes known in the art can be used (for example, as described in H. O. House. “Modern synthetic reactions” W. A. Benjamin, Inc., p.629-653, 1972).

EFFECT OF THE INVENTION

The present inventors performed the following tests in order to demonstrate the usefulness of the compound of the general formula (I) of the present invention.

TEST EXAMPLE 1 [Quantification of Aβ Peptide in Neuronal Culture from Rat Fetus Brain] (1)

Rat Primary Neuronal Culture

Primary neuronal cultures were prepared from cerebral cortices from embryonic day 18 Wistar rat (Charles River Japan, Yokohama, Japan). The embryos were aseptically removed from a pregnant rat under ether anesthesia. The brain was isolated from the embryo, and immersed in ice-cold L-15 medium (for example, Invitrogen Corp. Cat #11415-064, Carlsbad, Calif., USA, or SIGMA L1518, St. Louis. MO, USA). The cerebral cortex was collected under a stereoscopic microscope from the brain. The cerebral cortex fragments collected were subjected to enzyme treatment in an enzyme solution containing 0.25% trypsin (for example, Invitrogen Corp., Cat #15050-065, Carlsbad, Calif., USA) and 0.01% DNase (for example, Sigma D5025, St. Louis. MO, USA) at 37 C for 30 minutes to allow for cell dispersion. The enzyme reaction was terminated by addition of same volume of heat-inactivated horse serum. After centrifugation at 1500 rpm for 5 minutes, the supernatant was removed and 5-10 ml of medium was added to the cell pellet. Neurobasal Medium™ (Invitrogen Corp., Carlsbad, Calif., USA) supplemented with 2% B-27 supplement (Invitrogen Corp., Carlsbad, Calif., USA), 25 μM 2-mercaptoethanol (2-ME, WAKO, 139-06861, Osaka, Japan), 0.5 mM L-glutamine (for example, Invitrogen Corp., Cat # 25030-081, Carlsbad, Calif., USA), and 1% antibiotics-antimycotics (Invitrogen Corp., Cat # 15240-062, Carlsbad, Calif., USA) was used as the culture medium (Neurobasal/B27/2-ME). At the compound evaluation, the medium of the same composition not to add 2-ME alone (Neurobasal/B27) was used. The cell pellet was triturated by mild pipetting. Remaining cell pellet was removed by filtering through a 40-μm nylon mesh (Cell Strainer, Cat # 35-2340, Becton Dickinson Labware, Franklin Lakes, N.J., USA) and a neuronal cell suspension was obtained. The neuronal cell suspension was diluted with the Neurobasal/B27/2-ME medium and then plated in a volume of 100 μl/well to obtain an initial cell density of 5×10⁵ cells/cm² in a 96-well polystyrene plate pre-coated with poly-L or D-lysine (for example, Falcon MICROTEST Tissue culture plate 96 well flat bottom with low evaporation lid (Cat # 35-3075, Becton Dickinson Labware, Franklin Lakes, N.J., USA) coated with poly-L-lysine using the method shown below, or BIOCOAT™ cell environments Poly-D-lysine cell ware 96-well plate, Cat # 35-6461, Becton Dickinson Labware, Franklin Lakes, N.J., USA). Poly-L-lysine coating was carried out as follows. Poly-L-lysine (SIGMA P2636, St. Louis, Mo., USA) solution at 100 μg/ml was prepared aseptically with 0.15 M Borate buffer (pH 8.5). The solution was added to a 96-well polystyrene incubator at 50-100 μl/well and incubated at room temperature for one hour or more, or at 4 C overnight or longer. This was rinsed 4 or more times with sterile water, and then dried or rinsed with, for example, sterile PBS or medium, and used for plating cells. Cells were cultured for one day in an incubator of 5% CO₂-95% air at 37 C, the entire amount of the medium was exchanged with fresh Neurobasal/B27/2-ME, and the cells were then cultured for further 3 days.

Addition of Compounds

Drugs were added on day 4 of culture as follows. The entire amount of the medium was removed from culture well, and Neurobasal/B27 medium was added at 180 μl/well. The test compound dimethyl sulfoxide (hereinafter abbreviated as DMSO) solution was diluted with Neurobasal/B27 so than it would be 10-fold of the desired final concentration. A diluent was added at 20 μl/well and mixed well. The final concentration of DMSO was 1% or less. Only DMSO was added to the control group.

Sampling

After incubation for 3 days, the entire amount of the medium was collected as ELISA sample. This was used without any dilution for Aβx-42 measurement before subjecting to respective ELISA assays.

Evaluation of Cell Survival

Cell survival was evaluated by MTT assay. MTT assay was carried out according to the following protocols. Pre-warmed medium of 100 μl/well was added to the wells after collecting the medium. A solution of 8 mg/ml of MTT (SIGMA M2128, St. Louis, Mo., USA) dissolved in D-PBS(−) (Dulbecco's phosphate buffered Saline, SIGMA D8537, ST. Louis, Mo., USA) was added at 8 μl/well, and this was incubated in an incubator of 5% CO2-95% air at 37 C for 20 minutes. MTT solubilizing buffer was added to this at 100 μl/well, MTT formazan crystals were dissolved well in an incubator of 5% CO₂-95% air at 37 C, and absorbance was measured at 550 nm. MTT solubilizing buffer was prepared as follows. N, N′-dimethylformamide (for example, WAKO 045-02916, Osaka, Japan) and distilled water 250 ml each were mixed together. To this 100 g of SDS (sodium dodecyl sulfate (for example, sodium lauryl sulfate, WAKO 191-07145, Osaka, Japan)) was dissolved. Conc. HCl and conc. Acetic acid 350 μl each were added to allow for a final pH of about 4.7.

Upon measurement, wells without plating any cells containing only the medium and MTT solution were set as background (bkg). Individual measured values were subjected to the following formula and calculate the proportion against the control group (group without treatment with drugs, CTRL) (% of CTRL), to compare and evaluate cell survival. % of CTRL=(A550_sample−A550_(—) bkg)/(A550−CTRL−A550_(—) bkg)×100

-   (A550_sample: absorbance at 550 nm of sample well, -   A550_bkg: absorbance at 550 nm of background well, -   A550_CTRL: absorbance at 550 nm of control group well)     Aβ ELISA

For Aβ ELISA, Human Amyloid beta (1-42) Assay Kit (#17711 or #27711) from Immuno-Biological Laboratories, Co., Ltd. (IBL Co., Ltd.) were used. The methods were as described in the protocols recommended by the manufacturer (methods described in the attached document), except that Aβ calibration curve was created using beta-amyloid peptide 1-42, rat (Calbiochem, #171596 [Aβ42]. The results are shown as percentage to the Aβconcentration in the medium of control group (% of CTRL). The results are shown in Table 1.
